Chelsea have confirmed the signing of Matt Miazga from New York Red Bulls on a four-and-a-half-year contract.
The 20-yaer-old United States defender, was part of the New York side that finished top of the regular-season standings in Major League Soccer last year.
His arrival follows that of striker Alexandre Pato who has signed on loan for the rest of the season from Brazilian Club, Corinthians.
Miazga, a centre-half, said Chelsea was “the place to develop and learn from some of the best players in the world”.
He made 34 league appearances across three seasons with New York, with his solitary goal for the club coming in a derby victory over New York City FC last May.
